I need some help about the use of these plugins.

Let me explain you what I need :

The background is about rugby competitions.

I have on the left of the screen, a list of countries, and on the right, one or more divs that will contains a list of countries dragged and dropped on them.

Those divs are groups like 'group A' or 'Top 10'.

So I want to have the possibility of dragging countries from the first list to those divs and I also need them to be sortable.

Actually, I can drag a country from the left list to a group, I can drag a country between any group but I can't sort them. It's like I dragged and dropped again so that the country I selected is always sent to the end of the list.

I don't know if I am understandable because english is not my mother language, so I apologize.

If french people could help me, I will explain better in french.

Regards,

Eric.
